Credit: Saverio Bartalini, CNR Researchers from Istituto Nazionale di Ottica (INO), within Consiglio Nazionale delle Ricerche (CNR), Italy have demonstrated a new compact spectroscopic instrument that offers a highly sensitive optical method for detecting radiocarbon dioxide concentration, which can be used to carbon date fossils and archaeological artifacts.The instrument, which uses a new approach called saturated-absorption cavity ring-down (SCAR), is described in The Optical Society's journal for high impact research, Optica.

Tom Higham was lead author on the first paper which was concerned with the dating and analysis of the KC4 maxilla from the site of Kent's Cavern, in Devon (above left).

Radiocarbon dating was first attempted on the specimen in 1988, and a date of 30,900 ± 900 BP was obtained.

A new spectroscopic technique offers ultra-sensitive optical detection of radiocarbon dioxide.

The approach shows promise as a measurement tool in many fields, including carbon dating and greenhouse gas detection.

The team reanalyzed two milk teeth, which were discovered in the Grotta del Cavallo site in 1964 and previously classified as Neanderthal.
